AUTOMATIC STOP-MOTION FOR REELS.

SPECIFICATION forming part of Letters Patent No. 420,770, dated February 4, 1890. I

Application filed June 8, 1887- Serial No. 240,604. (No model.)

To all whom it may concern.-

Be it known that I, ORVILLE CARPENTER, of Attleborough, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Automatic Stop-Motions for Reels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to stop motions or mechanisms such as are employed for stopping a reel when the same has reeled a predetermined amount of yarn or thread.

Reeling-machines are used to reel a certain number of yards to the skein and the hank and a certain number of threads to the knot and a certain number of knots to the skein, and so on. It therefore becomes a requisite of these machines that the reels or swifts be revolved for a certain number of times before coming to rest, since at each revolution of the swift or reel a certain known quantity of thread is taken up and wound thereon.

There are now in common use reels in which the reels or swifts may be automatically stopped after they have performed a predetermined number of revolutions and reeled a predetermined quantity of yarn, and this automatic stopping is accomplished by means of a set of interchangeable gears, each of which is gaged so as to allow the machine to make a certain number of revolutions, when the gear then causes the machine to stop. These gears are used one at a time with the machine and have to be interchanged according to the amount of yarn to be reeled, and this construction therefore becomes obj ectionable.

The objects of my invention are to provide a stop-motion which will be automatic and will have the capacity of being easily and accurately adjusted, so as to adapt the same reel to wind different amounts of yarn or thread.

To the above purposes my invention consists, essentially, in an endless chain of ad; justable length and provided with a trip device and driving means for the chain, and in chain-wheels mounted on slides which are adjustable, so as to take up the slack or to slack the chain.

The invention further consists in the means for driving the chain from the main shaft and in the belt-shipping mechanism, which is periodically operated by the trip device on the chain, the adjustment of the length of the chain governing the period of the tripping.

In order that my invention may be fully understood, I have illustrated in the accompanying drawings and will proceed to describe the best forms thereof so far devised by me, with the knowledge that the same may be variously modified without, however, making a substantial departure from the spirit of my invention.

In the accompanying drawings, Figure 1 is a front view of a reel having my novel automatic stop-motion attached. Fig. 2 is a front view of a rear portion of the reel-frame, which is shown partly in section and partly broken away. This view shows the endless chain with the trip device mounted thereon and the sprocket-wheel for driving the chain and the adjustable slides provided with the chain-wheels and also aportion of the beltshipping mechanism. Fig. 3 is a view of a horizontal section, taken at a point just above the shipper-bar. Fig. 4 is a sectional view of the reel, taken on line at 4. in Fig. 1. Fig. 5 is an enlarged view of the trip device, together with an adjacent link of the chain. Fig. 6 is an enlarged View of j one of the adjustable slides provided with the chainwheels, and shown as mounted on the support-beam represented in cross-section. Fig. 7 is an enlarged view of the forked shipperrod and the end of the shipper-bar engaged by the rod, both the rod and bar being shown in portions.

In the said drawings, like numbers of reference designate corresponding parts throughout.

Referring to the drawings, the number 9 designates the machine-frame, in which is journaled the main shaft 10, provided with the belt-pulleys 12. The winding reel or swift 11 is mounted on the main shaft so as to revolve therewith. The belt-shipper l3 is secured to the shipper-bar 14, which sets loosely in the bearings 15, which are mounted on the frame 9, and this bar can be reciprocated on its length in the bearings 15, so as to cause the belt-shipper to ship the belt (which is not shown) over the pulleys 12, in order to stop and start the reel. Upon the inner side of the shipper-bar 14 is fixed the stud 16, which takes in the forked end of the shipper-rod 17, and this rod is rigidly attached to the rockshaft 18, which turns in the brackets 19, mounted upon the machine-frame. At the rear end of the rock-shaft 18 is secured the curved triparm 20, the tripping of which will effect the movement of the belt-shipper, as will be hereinafter described.

In order to accomplish the tripping of the trip-ar1n 20 atpredetermined periods, I have devised the following means: Across the frame 9 is mounted the turnable shaft 21, near the IS respective ends of which are keyed the pinion-wheel 22 and the sprocket-wheel The shaft 21 is driven from the main shaft 10 through means of the ehain-gcar 24, mounted on the shaft 10 and the chain-gear 25, which 20 turns with the worm-shaft 26, which is journaled in the frame 9 and works in mesh with the pinion 22 and through the chain belt 27, which connects the gears 2i and 25. Upon the support 28, which extends across the back 25 of the machine-frame, are placed the two slides 29 and 30, respectively, which consist each in a flat plate provided with two projections designed to embrace the support 28, and each projection is provided with a set- 30 screw 31, by means of which the slides may be adjusted at any points along the support. The slide 29 is provided with two idle chainwheels 32, and the slide 30 is provided with three similar idle chain-wheels The end- 3 5 less chain 3a is composed of the ordinary drive-chain links 35, (see Fig. 5,) which are readily detachable from each other, so that the chain may have links inserted in or taken from it in order to increase or decrease the length of the chain.

The trip device 36 consists in a detachable chain-link with a housing or tripping proj ection mounted upon it, and is designed to be passed under the end of the trip-arm 20 and 5 to trip the same,in order to operate the beltshipper, as will now be described; The endless chain 34; is of adjustable length, and is passed around the sprocket-wheel 23; thence the upper strand of the chain passes over the upper chain-wheels and 32, respectively, and mentoring upon itself it passes around the central chain-wheel 33 and about the lower chain-wheel 32, and thence it leads over the top of the lower chain-wheel 33 back to the sprocket-wheel 23, which has a positive motion given it, as before described, and serves to drive the chain in the direction of the arrows. By the travel of the chain the trip device is passed under the trip-arm 20 at each complete trip of the chain and raises the arm, so as to rock the rock-shaft l8 and oscillate the shipper-rod 17, which effects the shipping of the belt from the fast to the loose pulley and stops the reel.

6 5 By virtue of the arrangements of the slides 29 and 30, which are provided with the cl1ai11- wheels, the length of the chain may be increased or decreased, and the slides may be accordingly adjusted to take up the slack or to slack the chain. \Vhen the greatest length of chain is used, the slides will be adjusted at their greatest distance apart, one at each end of. the frame.

The gearing intermediate the main shaft and the shaft 21 may be so constructed that the shaft 21 may be made to turn the sprocketwheel sufficiently to advance the chain 34. the distance of one link at each revolution of the main shaft and reel, and thereby the reel will be permitted to make as many revolutions as there are links in the chain before the trip device will actuate the beltshipper. Thus by having so many links to represent arevolution of the reel the length of chain may be regulated, in order to allow the reelto make a predetermined number of revolutions, and thereby reel a predetermined quantity of yarn.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
